Well until yesterday I didn't know that Fedora didn't install /
configure any of these packages. I've installed tlp and powertop, I
didn't know powertop did anything other than monitor. I'll see what
powertop --auto-tune does. I don't even know if the tlp package has
enabled anything either. I wonder if having tlp installed and running
powertop --auto-tune will conflict / fight each other...
Time to try stuff out.
You might also look at tuned...
(I think it was mentioned early in the thread).
tuned-adm profile powersave
Also:

Of course it would be nice if this stuff just did the right thing and
you didn't have to run any commands or read any guides.
